What Is Schedule D Used For in Tax Reporting?

When selling stocks, real estate, or other investments, the IRS requires you to report gains or losses on your tax return. Schedule D helps taxpayers calculate and report these transactions. Properly completing this form ensures accurate tax liability and can reduce taxable income through loss deductions.

Understanding how different assets and holding periods affect taxation is essential for investors and anyone selling valuable property.

Capital Asset Classification

The IRS defines capital assets as most property owned for personal or investment purposes, including stocks, bonds, real estate, and collectibles. Business inventory, accounts receivable, and depreciable business property are excluded and treated differently for tax purposes.

Personal-use property, such as a home or vehicle, is also considered a capital asset, but tax treatment varies. Gains from selling a home may be taxable, but the IRS allows an exclusion of up to $250,000 for single filers and $500,000 for married couples if ownership and use tests are met. Losses on personal-use property, such as selling a car for less than its purchase price, are not deductible.

Investment assets, including stocks and cryptocurrency, are fully subject to capital gain and loss rules. The IRS classifies cryptocurrency as property, meaning it is taxed similarly to stocks rather than as ordinary income. When selling these assets, taxpayers must report the sale price, purchase price, and any associated costs to determine taxable gain or deductible loss.

Short-Term vs. Long-Term Gains

The length of time an asset is held before being sold determines its tax treatment. If sold within one year of purchase, any profit is a short-term capital gain, taxed at the seller’s ordinary income tax rate, which can be as high as 37% in 2024.

Holding an asset for more than a year qualifies any profit as a long-term capital gain, taxed at lower rates of 0%, 15%, or 20%, depending on taxable income. In 2024, a single filer with taxable income up to $47,025 pays 0% on long-term capital gains, while those earning between $47,026 and $518,900 are taxed at 15%. Only those exceeding $518,900 face the 20% rate.

Certain assets have different tax treatments. Collectibles like rare coins, art, and antiques are taxed at a maximum long-term capital gains rate of 28%. Real estate gains can be affected by depreciation recapture, which taxes the portion of the gain related to prior depreciation deductions at 25%. Additionally, high-income taxpayers may owe a 3.8% Net Investment Income Tax (NIIT) on capital gains if their modified adjusted gross income exceeds $200,000 for single filers or $250,000 for married couples filing jointly.

Calculating Adjusted Basis

The adjusted basis of an asset is necessary for accurately calculating capital gains or losses. It represents the original cost, modified by factors such as improvements, depreciation, and transaction costs.

For purchased assets, the starting point is the purchase price, including expenses like broker commissions, legal fees, or title insurance. If an asset is inherited, the basis is typically its fair market value on the date of the original owner’s death. Gifts follow different rules—if the asset has appreciated, the donor’s original basis carries over, but if it has depreciated, the recipient’s basis may be limited to the lower fair market value at the time of transfer.

Capital improvements, such as adding a new roof or remodeling a kitchen, increase the basis, while depreciation deductions on rental properties or business assets reduce it. Depreciation recapture requires that the recovered amount be taxed at a maximum rate of 25%.

Offsetting Gains with Capital Losses

Capital losses can offset taxable gains, reducing overall tax liability. The IRS requires taxpayers to apply losses against gains of the same type first—short-term losses offset short-term gains, while long-term losses reduce long-term gains. If losses exceed gains in one category, any remaining loss can then be applied to the other.

If total capital losses exceed total capital gains for the year, up to $3,000 ($1,500 for married individuals filing separately) can be deducted from ordinary income. Losses beyond this limit must be carried forward to future years.

Carryover of Excess Losses

When capital losses exceed the annual deduction limit, taxpayers can carry forward the remaining amount to future tax years. The carried-over losses retain their original classification, meaning short-term losses continue to offset short-term gains first, and long-term losses apply to long-term gains.

For example, if a taxpayer incurs a $10,000 net capital loss in a given year, they can deduct $3,000 against ordinary income and carry forward the remaining $7,000. In the following year, if they realize a $5,000 capital gain, the carried-over loss can offset the entire gain, leaving $2,000 available for future years. There is no expiration on capital loss carryforwards, but if a taxpayer dies before using the full carryover, any remaining losses are lost and cannot be transferred to heirs.

Special Cases for Certain Transactions

While most capital gains and losses follow standard tax rules, certain transactions receive unique treatment under IRS regulations.

Wash Sales

A wash sale occurs when a taxpayer sells a security at a loss and repurchases the same or a substantially identical security within 30 days before or after the sale. The IRS disallows the loss in the current year, instead adding it to the cost basis of the newly acquired security, deferring the deduction until the new security is sold. This rule prevents taxpayers from selling securities solely to generate tax-deductible losses while maintaining their investment positions.

Like-Kind Exchanges

Real estate investors can defer capital gains taxes through a like-kind exchange, also known as a 1031 exchange. This provision allows taxpayers to swap one investment property for another without immediately recognizing a taxable gain, as long as both properties are held for business or investment purposes. To qualify, the replacement property must be identified within 45 days of selling the original property, and the transaction must be completed within 180 days. While this strategy defers taxes, any gain is eventually realized when the replacement property is sold without another exchange.
